The Latest Cultivation Techniques and Methods Tutorial for Chebulic Myrobalan
Chebulic myrobalan, also known as Tibetan chebulic myrobalan, is the young fruit of Terminalia chebula, a plant in the genus Terminalia of the family Combretaceae. Generally in September to October, the young fruits are blown down by wind or picked, briefly boiled in boiling water, then taken out and sun-dried or oven-dried. It is a Chinese medicinal herb with extremely high medicinal value. So how should chebulic myrobalan be cultivated? Let's find out together.
1. Site Selection and Land Preparation
For the seedling nursery, choose a sunny, well-drained sandy loam soil in Jinshuiyuan, remove stones and weeds, plow deeply and harrow fine, then make raised beds. The width of the bed surface depends on the terrain. After making the beds, add sand to the surface and mix evenly, then set aside for use. For the planting site, choose a sunny open woodland hillside or hilly area, requiring fertile, loose soil, deep soil layer, and well-drained sandy loam; humus soil, forest podzolic soil, and alluvial soil are preferable. After selecting the site, first clear all weeds thoroughly, then dig planting holes. The size of the holes depends on the size of the seedlings, and the bottom of each hole should be applied with fully decomposed farmyard manure.
2. Planting Methods
There are many varieties of Terminalia chebula, and the fruit shapes and sizes differ greatly. When planting, select seeds from trees that are robust in growth, high-yielding, good in quality, and about 20 years old. In winter, pick plump, fully mature yellow fruits as seeds, and after picking, remove the seed kernels. Then carry out germination treatment. Germination generally uses sand storage treatment. When a large number of seeds have germinated, they can be sown. When sowing, open furrows on the bed surface, place one seed per spot at a plant spacing of 25 cm and a row spacing of 30 cm, cover with 3-4 cm of soil, then cover with rice straw and keep moist to facilitate seedling emergence. Generally, seedlings are raised for 2-3 years, and when the seedlings are about 1 m tall, they can be transplanted, preferably maintaining a row spacing of about 10-13 m.
3. Field Management
After seedling emergence, promptly remove the covering rice straw, and build shade sheds. A shade level of 30% is appropriate. When the seedlings are about 9 cm tall, apply dilute human and animal manure urine, and thereafter fertilize once every 1-2 months, with the concentration gradually increasing. In addition, frequently weed and loosen the soil. During the rainy season, pay attention to drainage and waterlogging prevention. During the young tree period, fertilize 2-3 times per year by opening furrows beside the trees and applying the fertilizer with irrigation. During the fruiting period of mature trees, apply fully decomposed farmyard manure to increase nutrients and promote flowering and fruiting. After harvesting the fruit, apply fertilizer once more so the trees quickly recover their growth vigor. Starting from the seedling stage, begin pruning the side branches on the stem to facilitate early transplanting out of the nursery. After transplanting, promptly pinch off growing tips, prune and shape the tree so it grows into a dwarfed plant, which facilitates fruit picking.
4. Pest and Disease Control
The scarab beetle is one of the main pests of Terminalia chebula. Its larvae bite and feed on the epidermis of the underground root system, causing root damage and inhibiting growth; the adults bite and feed on the young shoots and new leaves of Terminalia chebula, leaving the whole plant bare-topped or stripped bare. When the adults emerge and are active, light traps can be used to kill them, or their death-feigning behavior can be used by shaking the trees for manual capture. During the pest outbreak period, trichlorfon pesticide can also be used for control.
